-Tweaking the staff object allows to resize the staff:
+@funindex \startStaff
+@funindex startStaff
+@funindex \stopStaff
+@funindex stopStaff
+
+@notation{Ossia} staves can be set by creating a new simultaneous
+staff in the appropriate location:
 
 @lilypond[verbatim,quote]
-\new Staff \with {
-  fontSize = #-3
-  \override StaffSymbol #'staff-space = #(magstep -3)
-  \override StaffSymbol #'thickness = #(magstep -3)
-}
-\relative c {
-  \clef bass
-  c8 c c c  c c c c
+\new Staff \relative c'' {
+  c4 b d c
+  <<
+    { c4 b d c }
+    \new Staff { e4 d f e }
+  >>
+  c4 b c2
 }
 @end lilypond
 
 @noindent
-This involves shrinking the staff spaces, the staff lines and the
-font size by the factor 3.  You find a more precise explanation in
-@ref{Setting the staff size}.
+However, the above example is not what is usually desired.  To
+create ossia staves that are above the original staff, have no
+time signature or clef, and have a smaller font size, tweaks must
+be used.  The Learning Manual describes a specific technique to
+achieve this goal, beginning with
+@rlearning{Nesting music expressions}.
 
-The @emph{ossia} section in the next example are just put parallel
-to the main staff with @code{<<} and @code{>>} brackets.  The
-@emph{ossia} staff is stopped and started explicitely and white
-space is inserted with the @code{\skip} command.
+The following example uses the @code{alignAboveContext} property
+to align the ossia staff.  This method is most appropriate when
+only a few ossia staves are needed.
 
 @lilypond[verbatim,quote]
+\new Staff = main \relative c'' {
+  c4 b d c
+  <<
+    { c4 b d c }
+
+    \new Staff \with {
+      \remove "Time_signature_engraver"
+      alignAboveContext = #"main"
+      fontSize = #-3

+}
+@end lilypond
+
+If many isolated ossia staves are needed, creating an empty
+@code{Staff} context with a specific @emph{context id} may be more
+appropriate; the ossia staves may then be created by
+@emph{calling} this context and using @code{\startStaff} and
+@code{\stopStaff} at the desired locations.  The benefits of this
+method are more apparent if the piece is longer than the following

-as the @var{music}:
+Before a part can be quoted, the @code{\addQuote} command must be used
+to initialize the quoted fragment.  This command must be used in the
+toplevel scope.  The first argument is an identifying string, and the
+second is a music expression:
 
 @example
-clarinet = \relative c' @{
-  f4 fis g gis
+flute = \relative c'' @{
+  a4 gis g gis
 @}
-\addQuote clarinet @{ \clarinet @}
+\addQuote "flute" @{ \flute @}
 @end example
 
-After calling @code{\addQuote}, the quotation may then be done
-with @code{\quoteDuring} or @code{\cueDuring},
-
-@example
-\quoteDuring #@var{name} @var{music}
-@end example
+The @code{\quoteDuring} command is used to indicate the point where the
+quotation begins.  It is followed by two arguments: the name of the
+quoted voice, as defined with @code{\addQuote}, and a music expression
+that indicates the duration of the quote, usually spacer rests or
+multi-measure rests.  The corresponding music from the quoted voice is
+inserted into the music expression:
 
-During a part, a piece of music can be quoted with the
-@code{\quoteDuring} command.
+@lilypond[verbatim,quote]
+flute = \relative c'' {
+  a4 gis g gis
+}
+\addQuote "flute" { \flute }
 
-@example
-\quoteDuring #"clarinet" @{ s2. @}
-@end example
+\relative c' {
+  c4 cis \quoteDuring #"flute" { s2 }
+}
+@end lilypond
 
-This would cite three quarter notes (the duration of @code{s2.})
-of the previously added @code{clarinet} voice.
+If the music expression used for @code{\quoteDuring} contains
+anything but a spacer rest or multi-measure rest, a polyphonic
+situation is created, which is often not desirable:
 
-More precisely, it takes the current time-step of the part being
-printed, and extracts the notes at the corresponding point of the
-@code{\addQuote}d voice.  Therefore, the argument to
-@code{\addQuote} should be the entire part of the voice to be
-quoted, including any rests at the beginning.
+@lilypond[verbatim,quote]
+flute = \relative c'' {
+  a4 gis g gis
+}
+\addQuote "flute" { \flute }
 
-It is possible to use another music expression instead of
-@code{s}, thus creating a polyphonic section, but this may not
-always give the desired result.

+  c4 cis \quoteDuring #"flute" { c4 b }

-Quotations take into account the transposition of both source and
-target instruments, if they are specified using the
-@code{\transposition} command.

+The previous section explains how to create quotations.  The
+@code{\cueDuring} command is a more specialized form of
+@code{\quoteDuring}, being particularly useful for inserting cue
+notes into a part.  The syntax is as follows:
 
 @example
-  \cueDuring #@var{name} #@var{updown} @var{music}
+\cueDuring #@var{partname} #@var{voice} @var{music}
 @end example
 
-This will insert notes from the part @var{name} into a
-@code{Voice} called @code{cue}.  This happens simultaneously with
-@var{music}, which usually is a rest.  When the cue notes start,
-the staff in effect becomes polyphonic for a moment.  The argument
-@var{updown} determines whether the cue notes should be notated as
-a first or second voice.

+This command copies the corresponding measures from @var{partname}
+into a @code{CueVoice} context.  The @code{CueVoice} is created
